Dollar! Dollar! Where did it go?

Algebra Level 2

I saw a shirt for $ 97 \$97 . I borrowed $ 50 \$50 from mom and $ 50 \$50 from dad. I bought the shirt with $ 3 \$3 of change. I gave $ 1 \$1 to mom, $ 1 \$1 to dad, and kept $ 1 \$1 for myself. Now I owe my mom $ 49 \$49 and my dad $ 49 \$49 . $ 49 + $ 49 = $ 98 + \$49+\$49=\$98+ my $ 1 = $ 99 \$1=\$99 . Where did the other $ 1 \$1 go?

The logical thinking is flawed It went to the seller of the shirt My Mom took the $ 1 \$1 My Dad took the $ 1 \$1 It was wasted

$ 49 ⏟ \substack owe dad + $ 49 ⏟ \substack owe mom = $ 97 ⏟ \substack buy shirt + $ 1 ⏟ \substack you keep \large \underbrace{\$49}_{\substack{\text{owe} \\ \text{dad}}} +\underbrace{\$49}_{\substack{\text{owe} \\ \text{mom}}} = \underbrace{\$97}_{\substack{\text{buy} \\ \text{shirt}}} + \underbrace{\$1}_{\substack{\text{you} \\ \text{keep}}}

You borrowed a total of $98 from dad and mom to buy a $97 shirt and keep $1.
